SAWMILL.

Specification of Letters Patent.

Application filed October 22, 1907.

Patented Dec. 8, 1908.

Serial No. 398,614.

To all whom it may concern:

Be it known that I, FRANK O. WILLEY, a citizen of the United States, anda resident of Nestport, in the county of Decatur and State of Indiana,have invented a new and Improved Sawmill, of which the following is afull, clear, and exact description.

The object of this invention primarily is to provide in connection witha saw mill or other like cutting machine, a variable feed which is underthe absolute control of the operator, and which will give every ossiblerate of travel to the feed carriage wit in certain limits, in eitherdirection.

The invention further resides in certain novel features of constructionand combination of parts, as will be hereinafter described and set forthin the claims.

Reference is to be had to the accompanying drawings forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the views.

Figure 1 is a plan of a mill showing the guide rail or support of theframe partly broken away; Fig. 2 is a side elevation of the same andFig. 3 is a cross-section of the mill substantially on the line 33 ofFig. 1 looking in the direction of the arrow.

The frame of the mill to which I have shown my improvements applied iscomposed of cross-sills 5, 6 and 7 and longitudinal beams 8, 8 and 9, 9superposed thereon, the whole being mounted on a suitable base 10. Onthe beams 9, 9 are laid rails 11 on which travels the feed carriage 12,the latter being supported u on and movable over the rails on grooved weels 13.

In suitable bearings carried by the beams 8, between the sills 6 and 7,is journaled the saw arbor 14, carrying the saw or other like cutter 15between the adjacent beams 8 and 9; and at its opposite end a drivingpulley 16 and an adjacent friction-disk 17.

Arranged at substantially right-angles to the saw arbor, and journaledin bearings carried by the sills 6 and 7 at the outside of the frictiondisk 17, is a shaft 18 having drums 19 afliXed near its op osite ends,about which are reversely wound flexible lines or cables 20 which passto the feed carriage 12 and are directed oppositely to each other bypulleys 21, from which points they pass to the opposite ends of thecarriage and are secured.

Intermediate the drums 19 the shaft 18 pivotally supports a frame 22,the same belng constructed with upwardly-projecting arms having bearingsin which is journaled a shaft 23, the latter having a friction-wheel 24,filled with a friction fiber, slidably splined thereto, and furtherprovided with a gear 25 intermeshing with a somewhat larger gear 26secured to the shaft 18.

At the inside of the outer beam 8, bearings 27 are provided forrevolubly supporting a shaft 28 which is connected to the swinging orpivoted frame 22 through the intermediary of upwardly projecting arms 29and cross-bolts 30, the latter connecting the arms 29 with the arms ofthe frame 22, and having sufficient play such that the shaft 28 has alimited pivotal movement,.whereby the friction-wheel 24 may be movedinto and outof contact with the friction-disk 17.

' For normally holdin the friction-wheel separated or disengage from thefrictiondisk, the shaft 28 is provided with a depending arm 31 to whichis connected a tension spring 32 attached to some fixed portion of t emachine frame, as one of the longitudinal beams 8, best shown in Fig. 3.

The inward movement/of the arm 31, and consequently the separation ofthe frictionwheel from the friction-disk, is limited by a collar orother equivalent device 33 attached to a shifting-bar 34, the said barbeing slidably and revolubly mounted in suitable bear ings carried bythe cross-sill 6.

At that end of the shifting-bar adjacent to the frictional drive of thecarriage feed, it is provided with an upwardly+ rojecting arm 35, thelatter carrying a li 36 having a forked end which connects with the hubof the friction wheel by the aid of the usual collar or rin connection37, whereby the wheel may revo ve inde endently of the link, but isenforced to trave on the shaft 23 by revolving the shifting-bar 34.

At that end of the shifting-bar removed from the frictional drive of thefeeding mechanism, is fulcrumed an operating lever 38 which is extendeda slight distance therebelow where it is connected with a fulcrumed bar39, the latter being swingingly connected at its opposite end to themill frame, as best shown in Fig. 3.

From the construction described it is a parent that when the saw isdriven from t e pulley 16, the feeding mechanism for the carriage willremain in inaction until the operating lever is forced inwardly to bringthe friction-Wheel in cont act with the friction-disk at either side ofits center. At this time if the friction-wheel be in contact with thefrictiondisk at the proper side of its center, the car riage with thework thereon will be moved in the direction of the saw this rate oftravel being adapted to be changed to every possible speed in eitherdirection within certain limits by throwing the lever 38 sidewise, whenpressed inwardly, in one direction or the other thus causing thefriction-wheel to traverse the frictiondisk at either side of itscenter.

It is apparent that my improved feeding mechanism may be applied to sawmills different in construction from that herein shown and described,and that changes may be made in the detail construction of the feedingmechanism, without departing from the nature of the invention as definedin the claims annexed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent:

1. In a machine of the character described, a mandrel for carrying acutter, a carriage for carrying the work movable to and from thecutter,a shaft having drums provided with cables reversely wound thereon andoppositely connected to the carriage, means for driving the mandrel, afriction-disk carried by the mandrel, a frame sWi-ngingly mounted onsaid shaft, a second shaft journaled in the frame and geared with thefirst named shaft, a friction-wheel slidably splined to the second shaftand movable over the face of said i disk, and means for operating thesaid wheel.

2. In a machine of the character described, a mandrel for carrying acutter, a carriage for carrying the work movable to and from the cablesreversely wound thereon and oppositely connected to the carriage, meansfor I driving the mandrel, a friction-disk carried by the mandrel, aframe swingingly mounted on said shaft, a second shaft journaled in theframe and geared with the first-named shaft,

a friction-wheel slidably splined t0 the sec- 0nd shaft and movable overthe face of said disk, means operating to normally se arate the frictiondisk and friction whee and means operable to force the friction wheelinto contact with the friction-disk against the action of the lastnamedmeans and slide the friction wheel on its shaft.

3. In a machine of the character described, a cutter, a carriage forfeeding the work to the cutter, a friction-disk movable with the cutter,a shaft having drums provided with cables reversely wound thereabout andoppositely connected to said carriage, a frame swingingly mounted onsaid shaft, a frictionwheel for driving said shaft carried by said frameand movable over the face of said disk, means normally forcing saidframe in one di rection to separate the friction-wheel from thefriction-disk, and means operable to force the friction w'heel againstthe friction-disk against the action of the last named means and movethe friction wheel over the face of said disk.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.
